China's contribution to greenhouse gas emissions and its climate change strategies

China plays a significant role in global climate change, contributing approximately 22.7% of worldwide greenhouse gas (GHG) emissions. With nearly 80% of its energy derived from coal, the country faces a complex challenge in balancing economic growth with environmental sustainability.

Factors driving China's high GHG emissions

• Coal dependency - A major energy source due to vast domestic reserves, with reluctance to shift to oil or gas.
• Economic growth - Rapid industrialisation as an emerging nation has increased energy demand, particularly in heavy industries that consume large amounts of coal.

Climate change strategies in China

• Paris Agreement adoption - Committed to international efforts to combat climate change since 2016.
• National Action Plan on Climate Change - A set of policies aimed at promoting sustainable economic development, though it does not directly target reductions in energy use or industrial output.

China's efforts in forest conservation and restoration

Forests cover around 18% of China's land area, but much of the original subtropical and temperate rainforests have been converted to agricultural fields. In response, China has initiated significant efforts to restore and conserve its forest cover.

Forest conservation and restoration initiatives

• Largest global programme - China has launched the world's most extensive forest conservation and restoration initiative to offset its substantial carbon emissions.
• Carbon mitigation - Reforestation efforts are designed to absorb carbon dioxide, reducing the overall impact of GHG emissions.

China's management of fragile environments and coastal risks

China's vast landscape includes areas highly vulnerable to natural hazards, worsened by climate change. Coastal regions also face growing threats from rising sea levels, prompting specific management strategies.

Challenges in fragile environments

• Droughts and famines - Large regions frequently experience water shortages, leading to agricultural losses.
• Flooding hazards - A number of the world's deadliest floods have occurred in China, with climate change expected to increase their frequency and intensity.
• Water transfer solutions - Projects like the South-North Water Transfer aim to redirect floodwater to drought-affected areas, addressing regional imbalances.

Coastal risk management strategies

• Population at risk - Studies suggest that by the end of the century, around 50 million people could be threatened by coastal flooding if GHG emissions remain high.
• Coastal erosion - Shoreline retreat is already a pressing issue, expected to worsen with rising sea levels.
• Protective measures - Implementation of sea walls, land-use zoning, and restrictions on land reclamation to safeguard coastal zones.

Solomon Islands' vulnerability to climate change and its limited carbon emissions

The Solomon Islands, a small Pacific nation comprising six main islands and over 900 smaller ones, faces severe climate change impacts despite contributing minimally to global emissions. With a population of just over 600,000, its economy relies heavily on subsistence farming, fishing, and limited exports.

Carbon emissions in Solomon Islands

• Minimal contribution - Emissions are negligible on a global scale, primarily from burning fuelwood for domestic use and oil for transport.
• Deforestation impact - Once abundant tropical rainforests have been reduced due to timber exports and the need for farmland to replace areas lost to coastal erosion, slightly increasing local carbon output.

Solomon Islands' challenges with fragile environments and climate action constraints

The Solomon Islands is highly vulnerable to climate change, grappling with multiple environmental threats and limited resources to address them. Its fragile ecosystems and low-lying geography heighten the risks.

Environmental challenges in Solomon Islands

• Volcanic and seismic activity - Active volcanoes, frequent earthquakes, and tsunamis create unstable conditions.
• Deforestation consequences - Clear felling of forested volcanic slopes has led to landslides and soil erosion, degrading the landscape.
• Coastal erosion and sea level rise - Rising seas have already submerged five small uninhabited islands, while six others have lost significant land and villages to flooding, threatening scarce lowland areas.

Constraints on climate action

• Limited resources - Lack of financial capacity and technological access hinders effective responses to climate change.
• Dependency on external action - As a minor emitter, the Solomon Islands relies on larger nations to reduce global emissions, positioning its people as largely innocent victims of global warming.
• Climate action plan - Submitted a new strategy to the UN Convention on Climate Change in September 2015, though its impact remains uncertain given the scale of external challenges.
• Survival focus - The primary response is to adapt and endure as long as habitable land remains above sea level.
