On October 7, local time, a serious conflict broke out again between Palestine and Israel, which had been silent for some time. The Palestinian Islamic Resistance Movement (Hamas) suddenly launched a new round of military operations against Israel, firing thousands of rockets at Israel. In addition, Hamas militants also entered Israel and clashed with the Israeli army. Israel immediately declared a state of war and launched air strikes in response. The Palestinian-Israeli region is located in a sensitive zone in the Middle East, surrounded by major OPEC oil-producing countries such as Jordan, Saudi Arabia, Iran, the United Arab Emirates, and Kuwait. Its regional stability has a huge impact on maintaining the output and security of world oil and natural gas. The World Bank issued a warning on the 30th: If the Palestinian-Israeli conflict continues to escalate and expand, it will seriously affect global crude oil supply. In the most serious case, international oil prices may rise to close to US$160 per barrel, breaking the record high and further pushing up food prices. At the same time, Indermit Gill, chief economist of the World Bank, pointed out that the impact of the escalation of the Ukraine crisis on the global economy continues to this day. If the Palestinian-Israeli conflict expands, it will cause "the first double shock to global energy supply in decades." These have had a considerable impact on global climate change, sustainable development and the establishment of a low-carbon society.

Since entering the industrial society, global climate change has affected human survival and development, posing serious challenges to the sustainable development of the economy and society. Global climate warming has led to melting of glaciers, rising sea levels, degradation of ecosystems, and frequent natural disasters, deeply touches agriculture and food security, water resources security, energy security, ecological security and public health security, directly threatens human survival and development, and is not conducive to the construction of a low-carbon society.
At the Two Sessions in 2020, the dual carbon goals of “carbon peaking and carbon neutrality” were written into the government work report for the first time. In September of the same year, China solemnly announced to the world that it would strive to peak carbon emissions before 2030 and achieve carbon neutrality before 2060. At the 20th National Congress of the Communist Party of China in 2022, General Secretary Xi Jinping emphasized that “we must promote the construction of a beautiful China, adhere to the integrated protection and systematic management of mountains, rivers, forests, fields, lakes, grass and sand, and coordinate industrial structural adjustment, pollution control, ecological protection, and respond to climate change. Collaboratively promote carbon reduction, pollution reduction, green expansion and growth, and promote ecological priority, conservation and intensive, green and low-carbon development." Green development and low-carbon transformation have become an important trend in sustainable development in the world today.
A low-carbon society refers to creating a low-carbon life, developing a low-carbon economy, cultivating low-carbon cultural concepts of sustainable development, green environmental protection, and civilization, and forming an "olive-shaped" fair society with low-carbon consumption awareness. The key link in the construction of a low-carbon society is to continue to carry out scientific and technological innovation, continue to conduct research and development on the basis of relying on traditional energy (oil and natural gas), and integrate low-carbon new energy (water energy, wind energy, solar energy, Hydrogen energy, nuclear energy, etc.) and new low-carbon materials are used in all aspects of infrastructure construction in a low-carbon society.

Nanjing Sedray Industries Co., Ltd. adheres to corporate responsibility, keeps up with the theme of the world times, continues to innovate new materials, and finally develops a low-carbon FRP products series——Dragonbolt™ Composite Fasteners, Dragonbar™ Reinforced System, Dragonpro™ Fiberglass Building Products (including：(1) standard structural profiles, (2) FRP handrail systems, (3) FRP decks & floors, (4) FRP gratings and accessories), Dragonstrut™ Fiberglass Framing System (fiberglass support system) , Dragonpower™ Cable Management System.These products mainly use high performance reinforced glass fiber and corrosion resistant resin and necessary additives, through the pultrusion process and special processing technology to produce, compared with traditional materials (steel, aluminum, stainless steel, plastic), has a very obvious advantage:
1. Low VOCs content
Using new environmentally friendly materials, the content of volatile organic compounds is very low, which is friendly to the environment and people;
2. Low thermal expansion coefficient
The thermal conductivity of FRP products is 0.487 W /(M.K), only 1/100 of metal, specially suitable for outdoor construction, long-term high temperature will not cause skin burns;
3. Corrosion Resistance
FRP/GFRP products will never corrode, rust or lead to concrete spalling in the concrete structure;
4. High Chemical Resistance
Wastewater treatment, water treatment and desalination plants exposed to chemicals, water or high salt content of the environment, FRP/GFRP products can be very good resistance to the corrosion of the harsh environment;
5. Long Life Cycle
FRP/GFRP products are very durable, therefore, can reduce later maintenance and upgrade costs;
6. Light Weight and High Strength
The density of FRP reinforcement products is only 1/4 of that of metal materials. In modern times with high labor costs and oil prices, labor costs and transportation costs can be greatly reduced. At the same time, the frp rock bolts has strong thread load capacity, which can effectively substitute the use of metal rock bolts (slope support bolts);
7. Low Moisture Absorption
Unlike many plastics, the moisture absorption of FRP products is very low, even if it is soaked in water for a long time, there will be no obvious size change or mechanical property loss.
