The world is striving to cut greenhouse gas emissions and limit climate change. However, according to the Emissions Gap Report 2019 by UN, we are on the brink of missing the opportunity to limit global warming to 1.5°C, which is the critical level scientists say is associated with less devastating impacts than higher level of global warning. Scientists agree that to get on track to limit global temperature rise to 1.5°C, emissions must drop rapidly to 25 gigatons by 2030.
Time is short as there are too much to do, especially when we are even falling farther behind the target. Today, we need to reduce emissions by 7.6% every year, but even the most ambitious national climate action plans are far short of a 7.6% reduction.
In this endeavor we all have our parts of obligation to take up.
The top four emitters (China, USA, EU28 and India) contribute to over 55% of the total emissions over the last decade, excluding emissions from land-use change such as deforestation.
China’s existing policies to promote renewable energy throughout the country appear at the top of the global rankings. Subsidies to support wind and solar power generation in China are some of the highest in the world. Transformation in China is a significant emissions reduction opportunity: after a slowdown, China’s emissions grew 1.6% in 2018 to reach a high of 13.7 gigatons of CO2 equivalent.
In America, six states and territories have passed legislation setting state-wide goals for 100 per cent clean energy by 2045 or 2050. Over 100 American cities have made 100 per cent clean energy commitments. The US emits 13% of global emissions and had seen a gradual decline. However, emissions rose 2.5% in 2018, so there is opportunity for updated commitments and more actions.
The EU is likely to meet its NDC of GHG emission reductions of at least 40 per cent below 1990 levels by 2030 with its currently implemented policies. The EU revised its renewable energy target for 2030 from 27 per cent to 32 per cent and its efficiency target from 27 per cent to 32.5 per cent. Its 8.5% of global emissions has declined 1% per year across the last decade. Emissions declined 1.3% in 2018.
The Chinese government announced in March 2018 that it had achieved its Copenhagen emission reduction targets for 2020, which included reducing carbon intensity by 40 to 45 percent and raising the share of non-fossil fuel energy sources to 15 percent. According to Beijing, this achievement was largely due to the success of the carbon emissions trading system that was formalized in 2011. Undoubtedly a milestone, China’s carbon trading system is currently localized to the energy sector. Efforts to establish a national emissions cap and trade system have been delayed due to multiple technical problems, including a lack of reliable emissions data, but the applications of Internet of Things (IoT) may facilitate the collection of data in future.
China has planned to promote near-zero emission building development and integrate it into Government planning. The regulator driver for this may soon be in place. In this regard Thermal Energy Storage technology will definitely make contribution.
Hong Kong’s 2030 pleged target of carbon emission reduction between 3.3 and 3.8 tonnes per capita, has fallen 78 per cent short of the 2030 carbon emissions target set by C40 Cities for high emitting cities. Hong Kong is trailing behind its counterpart cities in renewable energy, energy efficiency, transitioning to electric mobility, and curbing greenhouse gas emissions.
Hong Kong has just seen its warmest year on record in 2019. Because of the hot weather, 90% of energy consumption in Hong Kong belongs to building, in which 30% is used for air-conditioning. The government rolls out a 600 Million program to promote energy saving and to help B&Ds implement energy saving projects. It is foreseeable that various kinds of energy saving solutions will flourish.
The average release of carbon into the atmosphere is known as the carbon footprint. Individuals, organizations and communities have their carbon footprints determined by their use of resources and the amount of greenhouse gases generated to support human activities. BOCA PCM-TES system are developing automatic real-time monitor and collection of chiller data, which will help our clients in carbon management and carbon audit. Together with our leading thermal energy storage technology especially applied in chiller system, we can really help Hong Kong to save a great level of electricity energy consumption in HVAC systems.
