1. Introduction

In this day and age, global climate change has become a global challenge that poses a serious threat to human society and the natural environment. The Sixth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) reveals the indisputable fact that the global average temperature has risen by about 1.1°C since the end of the 19th century, leading to an increase in the frequency and intensity of extreme weather events, as well as a significant loss of biodiversity [1]. This unprecedented climate change poses a significant threat to the global economy, social well-being, and the Earth's life support systems [2]. Against this backdrop, all sectors are looking for solutions to mitigate climate change, and the urgency and importance of action by the corporate sector is self-evident due to its significant role in global greenhouse gas emissions.

As one of the world's largest economic entities, corporations have the responsibility to reduce carbon emissions and achieve carbon neutrality and they also have enormous potential and resources to transform into sustainable business models. Carbon neutrality, i.e., balancing an organization's carbon footprint by reducing emissions or increasing carbon sinks, has become the goal of an increasing number of companies. One of the paths to achieve this goal is through carbon offsets and participation in the carbon credit market, which helps to mitigate the carbon footprint of companies and promotes the global transition to a low-carbon economy [3].

In carbon offsetting mechanisms, companies can offset their emissions by investing in forest conservation, reforestation, renewable energy and other carbon reduction projects. The global carbon credit market, which serves as a platform for measuring and trading these emissions reduction efforts, provides a flexible way for companies to reach their carbon neutrality targets. According to the World Bank, the carbon market is growing rapidly, providing an important economic incentive to meet global emissions reduction targets.

Among the many companies actively involved in carbon reduction, Google stands out for its unique environmental strategy and innovative practices. Since 2007, Google has been committed to achieving carbon neutrality in its business operations and has further committed to achieving 100% renewable energy use in its global operations by 2030. Google's Environmental Report details its efforts and progress toward these ambitious goals, demonstrating its leadership and innovation in driving corporate sustainability.

Google's carbon neutral strategy encompasses a range of measures, including investing heavily in wind and solar projects, adopting efficient data center management techniques, and implementing a strict green procurement policy [4]. Through these initiatives, Google has significantly reduced its carbon footprint and positively impacted the external environment, driving the acceptance and expansion of sustainable practices throughout the industry and society [5].

However, despite the significant progress made, Google faces a number of challenges in achieving its carbon neutrality goals. These challenges include the pace of technological innovation, the geographic distribution and cost of renewable energy, and the complexity and uncertainty of the global carbon market. It is the overcoming of these challenges that makes Google's carbon neutral strategy an expression of its corporate social responsibility and an important case study within the field of sustainable development.

By delving into Google's carbon neutral strategy and practice cases, this paper aims to provide a comprehensive analytical framework to understand how companies can achieve carbon neutrality through carbon offset mechanisms and participation in the carbon credit market. By analyzing Google's case, insights can be gained into the effectiveness and feasibility of carbon neutral strategies, as well as their long-term value to corporate sustainability and brand image.

2. Google's Carbon Offsetting Strategy: Principles and Implementation

Google has adopted a multifaceted strategy to achieve environmental sustainability, which demonstrates its commitment to reducing its carbon footprint through innovative strategies. These initiatives aim to meet the company's sustainability goals and set a precedent in the technology industry and influence the way it is practiced globally.

2.1. Rationale for Google's Carbon Offsetting Strategy

Google follows two core principles when selecting and evaluating carbon-neutral projects: practical effectiveness and additionality. These two principles are the theoretical cornerstones of Google's carbon offsetting strategy, ensuring that the company invests in projects that produce verifiable and significant emissions reductions, and that these are additionally realized as a result of Google's intervention. The Actual Effects Principle requires that projects must result in actual GHG reductions, while the Additivity Principle ensures that these reductions go beyond what would have been expected without Google's involvement.

In order to fully assess the benefits of potential projects, Google has implemented an evaluation framework that covers three dimensions: environmental, social and economic. In the environmental dimension, the assessment focuses on the potential positive impacts of the project on ecosystems and biodiversity, ensuring that the project will protect and restore the natural environment while reducing greenhouse gas emissions [1]. The social dimension focuses on the positive impacts of the project on the local community, including the creation of jobs, improvement of quality of life, and enhancement of environmental protection awareness. The economic dimension focuses on the cost-benefit analysis of the project to ensure that Google's investment can realize the maximum environmental value.

2.2. Implementation and Theoretical Application of Carbon Offset Programs

Through this strategy, Google has invested in a number of carbon offset projects around the world, including renewable energy investments, high-efficiency data centers, carbon offset projects, and technological innovations. The selection and implementation of these projects are based on the assessment framework described above, which ensures that each investment can have a truly positive impact on the environment.

Google is committed to reducing its carbon footprint through large-scale renewable energy projects. In 2019, Google announced its largest-ever renewable energy procurement, involving 1,600 MW of solar and wind projects. This move accelerated Google's goal of achieving 100% renewable energy use and boosted the global renewable energy market.

Additionally, the data centers Google uses around the world employ industry-leading technologies and management strategies to significantly improve energy efficiency. In particular, the company uses artificial intelligence algorithms to optimize the cooling systems of its data centers, resulting in a significant improvement in the energy use efficiency (PUE) of the data centers [6].

Google also offsets unavoidable emissions from its operations by investing in carbon offset programs. For example, Google supports reforestation projects in Africa, which absorbs large amounts of CO2 and restores local biodiversity and provides new economic opportunities for communities.

Meanwhile, Google is reducing carbon emissions from transportation by investing in electric cars and self-driving technology. For example, Waymo, a subsidiary of its parent company Alphabet, is developing self-driving technology, which improves urban mobility and reduces congestion and helps to reduce carbon emissions from transportation [7].

These strategies demonstrate how Google is combining innovative technologies and strategic investments to advance its sustainability goals. Through these initiatives, Google has achieved significant results in reducing its environmental impact and set an example of corporate sustainability on a global scale. Through the implementation of these programs, Google reduces carbon emissions globally and has a positive impact on biodiversity conservation and community development.

3. Research Methods

In order to discuss the impact of this strategy of Google, this study will use a structured cost-benefit analysis (CBA) for an in-depth exploration [8].

Annual Benefits: Calculated to be approximately $2.26 billion per year, including energy savings ($2.1 billion), revenue from carbon credits ($60 million), and additional revenue from brand equity and compliance ($100 million).Dot should be included after the sub subsection title number.

3.2.4. Net Present Value (NPV)

\( NPV=\sum _{t=0}^{T}\frac{{B_{t}}-{C_{t}}}{(1+r{)^{t}}} \)

Where:

\( {B_{t}} \) represents total revenue during year t;

\( {C_{t}} \) represents total costs during year t;

\( r \) is the discount rate 0.05;

\( T \) is the total number of years for which the analysis was conducted.

3.2.5. Sensitivity Analysis

Varying the discount rate: between 3% and 7% to see how a change in the discount rate affects the NPV.

Varying the initial investment and benefit realization: initial cost and annual benefit figures varied ±20% to test the robustness of the NPV under different financial conditions.

After sensitivity analysis, the NPVs all show positive values, indicating that Google's environmental strategies are beneficial to the sustainability of the business and financially favorable. These initiatives help Google to comply with global sustainability standards and enhance its competitiveness in a market that is increasingly focused on environmental responsibility. Given that these strategies are expected to have a positive net financial impact over a ten-year period, the analysis supports the continuation of these strategies.

3.3. Discussion

In analyzing how Google Inc. is addressing climate change through innovative strategies, this study reveals the far-reaching implications and practical effects of its environmental initiatives. Although the study provides a positive assessment of the cost-effectiveness of Google's environmental strategies and reveals the positive net present value of Google's environmental strategies, there are still some limitations. First, this analysis relies on the current market price and policy environment, which may change over time, thus affecting the accuracy and relevance of the analysis. Second, the forecasting model may fail to adequately account for the pace and direction of technological advances that could significantly affect the cost and efficiency of renewable energy.
