From renewable energy and the effect of hydrogen, to clean the heating and cooling, etc., around these topics, we will analyze the current challenges and solutions, and how should we work together to tackle climate change.

In the recently released report, the lower levels of the global annual emissions this issue, the UN's intergovernmental panel on climate change (IPCC) has been clear about the challenge for us - if the forecast on the basis of relatively safe, achieve 1.5 ° C temperature, we have only 300 billion tonnes of carbon dioxide available carbon budget.At present, the global annual emissions by about 36 billion tonnes of carbon dioxide, this means that if carbon emissions continue to rise at the rate of now, our carbon budget will be exhausted in just over nine years.And over budget will lead to global temperature rise by more than 1.5 degrees Celsius.

The challenges of net zero emission, we need to race against the clock.Across the world, this is an unprecedented, goal-driven and wide-ranging reforms.We need to have a foothold in the long run, quickly and aggressively take measures, aiming at increase in human activities all aspects of the carbon emissions change;At the same time we also should be the human activity as an interconnected system, otherwise you will lose valuable time.

First of all, we need to thoroughly understand the decarburization attributes of the industry.Some 73% of global carbon dioxide emissions from energy due to the economic development, including heating and passenger traffic, freight, etc.Emissions, followed by the global food system accounts for 18% of the total global emissions, covers the problem such as deforestation and agricultural land.After is, cement and petrochemical heavy industry accounts for about 5% of the total global emissions.Finally, the sewage and landfill waste decomposition of carbon emissions, accounts for about 3%.

After making a net zero emissions, the industry still is closely related to our life.After decades of development and evolution, which has become a series of interconnected system, both in terms of technology, supply chain, market, or the policy point of view to look, between them are inseparable.Though the industry development in the world is very different, between the obvious differences, but also has the close relation between each other.Therefore, if you want to change this situation, means to break the status quo, very challenging.

Considering the complexity of these industries and interdependence, we need to adopt the method of integration, not only for a business.For example, in the past decade, as the solar panels (85%), onshore wind (56%) and offshore wind (48%) costs have fallen sharply, renewable energy power generation industry has achieved great success.But this is just one of the problems we face.The next question is how to embed the renewable energy generation into the whole energy system.For example, how to provide transportation, heating, and some industrial processes cleaner alternative energy?The rapid development of an industry how to benefit other industries.

Therefore, we will in the next few weeks on the analysis of the key areas for "integration" and thinking.We believe that through these topics of discussion, but with the help of some inspiration to the net to realize zero discharge.At the same time, we will also analyze the challenges and solutions, and how it can be applied to the associated in all walks of life.We share the following:

• Large-scale renewable energy power generation and cost-effective grid power- such as offshore wind technology costs down quickly and then to consider the important problem is how to balance the cost, to embed the renewable energy power generation power and energy systems.
• Develop and enhance energy system flexibility- as the global energy system of supply and demand side gradually get rid of the dependence on fossil fuels plant, energy system whether to cost-effective, safe, flexible way to cope with change is very important.
• Introducing and popularizing green refrigeration- as the temperature rise of the problems of climate change and global changes in dietary patterns, how to don't affect climate or minimum under the condition of climate, balance of foods, drugs and comfort refrigeration fair use is the key.
• To clean the heating transformation- although there are some solutions such as heat pumps, biomass boiler can be gradually replace the existing heating way, but because of the limitation of cost, how to commercialization remains a problem.
• To realize the sustainable development of the hydrogen- we should explore a more strategic as soon as possible, inclusive of the hydrogen use method, make its can play an important complementary role in the process of decarbonization.
• Planning and development of carbon dioxide removal (CDR) solution- the point is through a deeper understanding of the climate system response carbon removal, carbon removal strategy, with the global temperature rise control in the range of "acceptable" as a benchmark, carbon dioxide emissions standards.
• Justice transformation- in multiple industries in the process of transforming into the net zero emissions, inclusive approach is to guarantee the global fair share the key to sharing costs and benefits.

This series theme the starting point of the article, not only in view of the above topics to discuss and provide strategic direction, and to call for individuals and institutions around the world to cooperate with our search for solutions to cope with the challenge of net zero.

Of course, the process of transforming to net zero emissions must adhere to justice, at the same time to be pragmatic.The key is we need to understand, although the transition strategy will ultimately help each country and community to find sustainable development path, but still need to cost, political will, or social acceptability, etc to make trade-offs.

In order to achieve the goal as soon as possible, we need to think about the problem of climate change more macro.The way of making a net zero emissions must be full of challenges, not everything goes well.We only move forward, hand in hand cooperation, can achieve the goal as soon as possible.
