Introduction

The decarbonisation of the economy is a crucial goal for mitigating climate change and achieving sustainable development. Decarbonisation refers to the process of reducing or eliminating carbon emissions from various sectors of the economy, including energy, transport, industry, agriculture, and buildings. The Services to Buildings and Landscape Activities sector is a significant contributor to carbon emissions, accounting for about 10% of global greenhouse gas (GHG) emissions. This article explores the concept of decarbonisation in the Services to Buildings and Landscape Activities sector, its importance, main sources of carbon emissions, strategies for reducing emissions, challenges, and implications.

What is Decarbonisation in Services to Buildings and Landscape Activities Sector and Why is it Important?

The Services to Buildings and Landscape Activities sector comprises a wide range of activities, including construction, maintenance, repair, and cleaning of buildings, parks, gardens, and other outdoor spaces. These activities involve the use of various materials, equipment, and energy sources that emit carbon dioxide (CO2) and other GHGs. Decarbonisation in this sector refers to the reduction or elimination of these emissions through the adoption of low-carbon technologies, practices, and policies.

The importance of decarbonisation in the Services to Buildings and Landscape Activities sector lies in its significant contribution to global GHG emissions and its potential for reducing these emissions. According to the International Energy Agency (IEA), the Services sector, including buildings and transport, accounts for about 40% of global energy-related CO2 emissions. In the European Union (EU), buildings alone account for 36% of total GHG emissions, making it the largest emitter among all sectors. Therefore, decarbonising the Services sector, including buildings and landscape activities, is essential for achieving the EU's target of net-zero emissions by 2050 and the Paris Agreement's goal of limiting global warming to below 2°C.

What are the Main Sources of Carbon Emissions in Services to Buildings and Landscape Activities Sector?

The main sources of carbon emissions in the Services to Buildings and Landscape Activities sector are energy consumption, materials, and waste. Energy consumption is the largest contributor to carbon emissions, accounting for about 80% of total emissions in this sector. The energy used in buildings and landscape activities comes from various sources, including electricity, natural gas, oil, and biomass. The combustion of these fuels releases CO2 and other GHGs into the atmosphere.

Materials used in construction, maintenance, and repair of buildings and landscapes also contribute to carbon emissions. The production, transportation, and disposal of these materials emit GHGs, such as CO2, methane (CH4), and nitrous oxide (N2O). For instance, the production of cement, which is a key material in construction, accounts for about 7% of global CO2 emissions. Similarly, the use of synthetic fertilisers in landscaping activities releases N2O, a potent GHG.

Waste generated from buildings and landscape activities is another source of carbon emissions. The disposal of waste in landfills produces CH4, a potent GHG that is 28 times more potent than CO2 over a 100-year period. The incineration of waste also emits CO2 and other pollutants, such as nitrogen oxides (NOx) and sulphur dioxide (SO2).

How Can We Reduce Carbon Emissions in Services to Buildings and Landscape Activities Sector?

Reducing carbon emissions in the Services to Buildings and Landscape Activities sector requires a combination of measures, including energy efficiency, renewable energy, low-carbon materials, waste reduction, and circular economy. Some of the strategies for reducing emissions are:

1. Energy Efficiency: Improving the energy efficiency of buildings and landscape activities is the most effective way to reduce carbon emissions. This can be achieved through measures such as insulation, efficient lighting, and heating systems, and smart controls. Energy-efficient buildings can reduce energy consumption by up to 50%, resulting in significant GHG emissions reductions.
2. Renewable Energy: The use of renewable energy sources, such as solar, wind, and geothermal, can also reduce carbon emissions in the Services sector. Renewable energy can provide clean and sustainable energy for buildings and landscape activities, reducing reliance on fossil fuels.
3. Low-Carbon Materials: The use of low-carbon materials, such as recycled and sustainable materials, can reduce carbon emissions from construction and landscaping activities. For instance, using recycled concrete instead of virgin concrete can reduce CO2 emissions by up to 50%.
4. Waste Reduction: Reducing waste generated from buildings and landscape activities can also reduce carbon emissions. This can be achieved through measures such as recycling, composting, and waste reduction programmes.
5. Circular Economy: Adopting a circular economy approach can also reduce carbon emissions in the Services sector. This involves designing buildings and landscapes to be more sustainable and resource-efficient, reducing waste and emissions, and promoting the reuse and recycling of materials.

What are the Challenges Facing Decarbonisation in Services to Buildings and Landscape Activities Sector?
